In this paper, we present the astrophotometric catalogues of 56 globular clusters and one
open cluster. Astrometry and photometry are mainly based on images collected within the …

We present wide-field, ground-based Johnson–Cousins UBVRI photometry for 48 Galactic
globular clusters based on about 90 000 public and proprietary images. The photometry is …

We use images collected with the near-infrared camera (NIRCam) onboard the JWST and
with the Hubble Space Telescope (HST) to investigate multiple populations at the bottom of …

In the third paper of this series aimed at developing the tools for analysing resolved stellar
populations using the cameras on board of the James Webb Space Telescope (JWST), we …

We develop and disseminate effective point-spread functions and geometric-distortion
solutions for high-precision astrometry and photometry with the JWST NIRISS instrument …

The Wide-Field Infrared Space Telescope (WFIRST) will be capable of delivering precise
astrometry for faint sources over the enormous field of view of its main camera, the Wide …

We analyze four epochs of Hubble Space Telescope imaging over 18 yr for the Draco dwarf
spheroidal galaxy. We measure precise proper motions for hundreds of stars and combine …

ABSTRACT HP 1 is an α-enhanced and moderately metal-poor bulge globular cluster with a
blue horizontal branch. These combined characteristics make it a probable relic of the early …

Aims. We present the photometric analysis of the external regions of three Galactic globular
clusters: NGC 6121, NGC 6397, and NGC 6752. The main goal is the characterization of …

Context. Wide binaries are a potential pathway for the formation of hot Jupiters. The binary
fraction among host stars is an important discriminator between competing formation …
